A display panel including a first capacitor and a second capacitor is disclosed. The first and second capacitors boost a second driving voltage from a driving chip and apply the boosted second driving voltage to the driving chip. The driving chip receives the boosted second driving voltage and outputs a first driving voltage to drive the display panel. Thus, the display panel does not require any additional capacitor for boosting the second driving voltage, thereby reducing a thickness and a manufacturing cost of the display panel.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of manufacturing a display panel, comprising: forming a first metal layer on a substrate; patterning the first metal layer to form a gate electrode in a first area on which an image is displayed and a first electrode of a first capacitor in a second area surrounding the first area; forming an insulating layer on the substrate on which the gate electrode and the first electrode are formed; and forming a second electrode of the first capacitor on the insulating layer corresponding to the second area, forming a second capacitor having a different capacitance from the first capacitor in a third area adjacent to the second area.
2. The method of claim 1 , further comprising: forming a second metal layer on the insulating layer; and patterning the second metal layer to form a source electrode and a drain electrode in the first area and a second electrode of the first capacitor in the second area.
3. The method of claim 1 , further comprising: forming a second metal layer on the insulating layer; patterning the second metal layer to form a source electrode and a drain electrode in the first area; forming a third metal layer on the insulating layer on which the source and drain electrodes are formed; and patterning the third metal layer to form a pixel electrode in the first area and a second electrode of the first capacitor in the second area.
4. A method of manufacturing a display panel, comprising: forming a first metal layer on a substrate; patterning the first metal layer to form a source electrode and a drain electrode in a first area on which an image is displayed and a first electrode of a first capacitor in a second area surrounding the first area; forming an insulating layer on the substrate on which the source electrode, the drain electrode, and the first electrode are formed; forming a second metal layer on the insulating layer; and patterning the second metal layer to form a pixel electrode in the first area and a second electrode of the first capacitor in the second area, forming a second capacitor having a different capacitance from the first capacitor in a third area adjacent to the second area.
